Humans continue to develop – in fact, they are doing so at a faster rate than at least 250 years.
This is the conclusion of scientists in Australia, who found that more and more people now have an average artery in their arms, and more people are now born without wisdom teeth, among other findings.
The research was published in the Journal of Anatomy last month.
A one-time rare medieval artery, considered primarily a “fetal structure”, complements the radial and ulnar arteries, increasing overall blood flow and hand. Flinders University Anatomy professor Tegan Lucas and Adelaide medical-science professors Maciej Heneberg and Jalia Kumaratilek say their work suggests that medieval arteries will be found in most humans by the turn of the century.
In the video below, Lucas summarizes the research.
“Since the 18th century, anatomists have been studying the prevalence of this artery in adults, and from our study it is clearly growing,” Lucas said in a statement through Flinders University in Adelaide. “This trend was around 10% among people born in the mid-1880s compared to those born in the late 20th century, so when it comes to development, it is a significant increase in a fairly short period of time.”
The Journal of Anatomy study states that “if still born 80 years of age, all of this will carry a medieval artery, if this trend continues. When the prevalence of the medieval artery is 50% or more” Is, it should not be considered as a variant, but as a ‘normal’ human structure. “
The study also concludes that human faces are becoming smaller and jaws smaller, resulting in more people being born without wisdom teeth.
Research found other changes occurring in humans, including extra bones and bone connections in the legs and feet.
Lucas says that such “microevolution” indicates that humans are “evolving at a faster pace than at any point in the last 250 years.”
